May 05, 2010  Aggregate crushing value = (W2 x 100) / (W1-W) W2 =Weight of fraction passing through the appropriate sieve. W1-W =Weight of surface dry sample. The mean of two result to nearest whole number is the aggregate crushing value. Result. The aggregate crushing value of the given sample= Aggregate Crushing Values

##### DETERMINATION OF AGGREGATE CRUSHING VALUE

The aggregate crushing value gives a relative measure of the resistance of an aggregate to crushing under a gradually applied compressive load. Crushing value is a measure of the strength of the aggregate. The aggregates should therefore have minimum crushing value. 3. APPARATUS

Objective: 1. Determine the aggregate crushing value of coarse aggregate. 2. Assess suitability of coarse aggregates for use in different types of road. Theory: The “aggregate crushing value” give a relative measure of the resistance of an aggregate to crushing

##### METHOD B1 THE DETERMINATION OF THE AGGREGATE

The aggregate crushing value (ACV) of an aggregate is the mass of material, expressed as a percentage of the test sample. which is crushed finer than a 2,36 mm sieve when a sample of aggregate passing the 13,2 mm and retained on the 9,50 mm sieve is subjected to crushing under a gradually applied compressive load of 400 kN. 2 APPARATUS 2.1 An ...

In this laboratory activity students will be exposed to aggregate crushing value and flakiness index of aggregate. Objectives To determine the aggregate crushing value. Learning Outcome At the end of the laboratory activity, students would be able to: 1. Find out the ACV of given sample. 2. Analyze data

##### How to Find Aggregate Crushing Value and Its Test Procedure?

The sample is then sieved on 2.36 mm IS sieve until no further significant amount passes in one minute. The fraction passing the sieve is weighed to nearest accuracy of 0.1g (W2) The crushed aggregates (W2) is expressed as % of the total weight of sample (W1), which is the crushing value of the aggregate. Aggregate crushing value

##### RELATIONSHIP BETWEEN AGGREGATE CRUSHING VALUE

between aggregate crushing value (ACV) and ten percent fines aggregate crushing value (TFV) for some aggregates in Nigeria. Such a mathematical relationship, usually established through regression modelling on data collected, is useful in saving time and money cost on site through estimating one variable when another is known.

##### Aggregate crushing value test Step by Step Procedure ...

The average crushing value in the different tests is the actual crushing value of aggregate. Important points to remember. It is recommended that the crushing value of aggregate should be less than 30%. If it is more than 30 % then 10% finer aggregate is suggested to use. The aggregate whose crushing value

##### Introduction on aggregate crushing value apparatus

Dec 19, 2014  After this, the load is released. (v) The sample is then sieved through a 2.36mm IS Sieve and the fraction passing through the sieve is weighed (Weight 'B'). (vi) Two tests should be conducted. 7. CALCULATION: • Aggregate crushing value =

##### Calculate the average crushing value of aggregate using ...

To find average crushing value of given aggregate. Average %ACV = $\frac{ (18.43+17.89+18.78)}{/3}$ X 100. Average %ACV = 18.36%. Suitability: As the % ACV is 18.36%,which is less than 30%, hence the given sample of aggregate is suitable for non-wearing surfaces like roadways, runways etc.
